Zimbabwe all-rounder Malcolm Waller has been suspended from bowling after his action was found to be illegal.
Wallace was reported to the International Cricket Council (ICC) following Zimbabwe's second Test with Bangladesh last month.
The 30-year-old's action was analysed by the ICC in South Africa earlier this month and was found to exceed the 15 degrees level of tolerance allowed.
A statement on the ICC website read: "The International Cricket Council today confirmed that an independent analysis has found the bowling action of Zimbabwe's Malcolm Waller to be illegal and, as such, the off-spinner has been suspended from bowling in international cricket with immediate effect.
"The analysis revealed that all of his off-spin deliveries exceeded the 15 degrees level of tolerance permitted under the regulations.
"Waller was reported after the second Test against Bangladesh in Khulna last month. The analysis was performed by the ICC's accredited team of Human Movement Specialists at the High Performance Centre in Pretoria on 7 December.
"Waller can apply for a re-assessment after modifying his bowling action in accordance with clause 2.4 of the Regulations for the Review of Bowlers Reported with Suspected Illegal Bowling Actions."
Named in Zimbabwe's 30-man provisional squad for the 2015 Cricket World Cup, which starts in February, Waller has regularly been used as a bowling option by his country in the past year.
In nine Test matches, Waller has taken six wickets at an average of 22.
